Not worth the price

Please improve quality. I bought the product to wear during winters in the UK. Although it is made of merino wool and does the job, there is a big hole in one of the sleeves.

No advice yet but for me is great !

Excellent value!

Merino wool base layer at less than half the price of Icebreaker. 2 sets (top and bottom) served me very well over 8 days walking around in Tokyo this winter. Good product, highly recommended!

Love this base layer

Used it on a 6 day hike to Pindari glacier, in the Himalayas. Gained altitude of 12,000 feet. Great base layer. Fits perfectly and feels warm when weather is chilly. This is the first base layer I have really enjoyed wearing (have been hiking in synthetic base layers since 2010).

Cumple su funcion

Lo uso como segunda capa cuando el tiempo es frío y salgo a andar un buen rato, me mantiene caliente y seco.

Esta bien, la recomiendo.

Tengo otras camisetas con lana de merina de otra marca qué son más caras, pero ésta está a la altura en calidad. Transpira muy bien, abriga y no huele. La recomiendo.

Sizing and fit

This T-shirt has a slightly fitted sporty cut that facilitates moisture transfer toward the outside of the fabric.

Origin of the wool

We only use wool from Merino sheep bred on farms in South Africa that do not practice mulesing. Merino wool is a renewable material ; it grows back after each shearing. We use very fine Merino wool for this base layer (18.5 microns): it is very soft and doesn't itch. More information:


A new yarn structure in which a polyamide yarn forms a thin sheath that protects the merino wool fibers against friction and cuts

Why a bag?

We decided to sell this base layer in a small bag. We want to avoid packing it in a bag that is thrown away after you have bought it!! The next time you go to the mountains, you can reuse this bag to keep socks, a micro-fiber towel or any other object. You choose its second life!!



Product testing

In November 2018, 8 backpackers (4 men and 4 women) and part of the Forclaz design team tested this T-shirt for 4 days in the Southern French Alps (Lus La Croix Haute). You can expect wind, rain, a bit of snow, a bivouac... and a lot of fun! We were able to make the final modifications and validate it for use in mountain backpacking.
